Pterygium Excision
Pterygium is an abnormal growth of conjunctival tissue onto the surface of the cornea, most commonly caused by prolonged exposure to ultraviolet light. It is more prevalent in individuals who grew up in regions closer to the equator or who spend significant time outdoors. Symptoms include irritation, burning, a foreign body sensation, tearing, light sensitivity, and redness. In more advanced cases, pterygium can distort the corneal surface and cause blurred or partial vision loss. If left untreated, a growing pterygium can permanently scar the cornea and reduce vision.
Mild cases may be managed with frequent lubrication, but moderate to severe or progressively growing pterygia should be surgically removed before irreversible corneal scarring occurs. Princeton Eye Group performs state-of-the-art pterygium excision using sutureless techniques, including autologous conjunctival grafting and amniotic membrane grafting. These procedures use tissue glue rather than sutures, minimizing discomfort and recovery time while significantly reducing the risk of recurrence compared to older excision techniques.
Corneal Scar Treatment
Corneal scarring can result from infections, including herpes simplex keratitis, bacterial or fungal keratitis, trauma, chemical injury, or prior surgical procedures. Depending on the location, depth, and density of the scar, treatment options range from specialty contact lenses and phototherapeutic keratectomy (PTK) to lamellar or full-thickness corneal transplantation. Our corneal specialists perform a thorough evaluation to determine the most conservative, effective approach for each patient, with the goal of maximizing visual recovery while minimizing surgical risk.
Anterior Segment Surgery
Damage to the iris, pupil, lens, or other structures at the front of the eye may cause glare, light sensitivity, distorted vision, or reduced vision. These problems may result from trauma, congenital abnormalities, or complications of previous eye surgery.
Depending on the structures involved, treatment may include iris suturing, pupiloplasty, custom artificial iris implantation, repositioning or fixation of an unstable intraocular lens, intraocular lens exchange, or repair of several structures during one operation. When a lens has shifted farther toward the back of the eye, the vitreous is involved, or retinal disease affects the treatment plan, evaluation or coordinated care with a retina specialist may be recommended.
Ocular Surface Reconstruction
Disease, injury, scarring, or previous surgery can disrupt the corneal and conjunctival surface. Conditions such as conjunctival tumors, symblepharon, cicatricial scarring, limbal stem cell deficiency, and persistent epithelial defects may require specialized medical and surgical care to protect the eye and restore a more stable surface.
Treatment is individualized and may include lesion removal, scar release, conjunctival grafting, amniotic membrane transplantation, or Descemet membrane anterior keratoplasty (DMAK) with a BrightMEM corneal allograft in selected cases. These procedures are used to support healing, improve comfort, protect the cornea, and improve vision when possible.
